从旅行照片中删掉游客
Deleting tourists from your travel photos
照相机放三脚架上
Put your camera on a tripod
每10秒拍15张照片
Take about 15 pictures about every 10 seconds
在Photoshop中从“文件-脚本-统计”中打开所有照片，选“中间值”。
Open them all in Photoshop from File->Scripts->Statistics. Choose "median".
外行人的逻辑：取“中间值”时只有15张照片像素相同那些不属于移动物体（游客）的才能被覆盖。
Layman's Logic: Only constant pixels in all 15 images are those, that don't belong to the moving objects(tourists) and get cancelled out while taking median.
人们认为这在理论上和实际上都行得通。
People agree that it works both in theory and practice.
很明显照片越多最后出来的效果越好。
Obviously more number of images will improve the quality of output.
